I want to install Linux on my desktop and I decided for Debian. I know that Knoppix is based on Debian unstable/testing.

Once I installed Knoppix 3.3 on my desktop and i always got problems after apt-get distupgrade. I guess the reason for this is that Knoppix "main idea" is a Live-CD and no HD-install?

So, if I want to have a Debian-Linux installation on my HD - is it better to install Debian Sarge or is the new Knoppix 3.6 developed so far that i can install it on HD, make updates etc. without having any problems?
